Immunohistochemistry and immunofluorescent immunostaining data shows that the cytoplasm and membrane of tumor cells and the stromal cells surrounding the tumor cells were both positive for CD73 (Fig. 7b, and e) and that the membrane of the tumor cells were positive for emmprin; however emmprin was not expressed in the stromal cells (Fig. 7c and f). The gene discussed is BSG; the disease is neoplasm.
